"METAL-BENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 643,354, dated February13, I900.

Application filed April 10, 1899.

To 001% whom it may concern:

Be it known that we, MAX W. HENIUS and JOHN HERROLD, citizens of theUnited States, and residents of New York, in the county of KingsandState of New York, have invented with a portion of the device forfeeding the corset-steels broken away. Fig. 3 is a vertical section fromfront to rear through the machine in the plane of the line 3 3 of Fig.2. Fig. 4 is a top plan view of the machine with the rotary table, whichcarries the corset steel I hoppers and the stationary table, removed.

Fig. 5 is a front view of the machine, the upper portions of the hoppersbeing broken away. Fig. 6 is a rear view of thesame. Fig. 7 is a planview with the top of the frame removed. Fig. Sis a vertical section fromfront to .rear through the upper portion of the machine, the parts beingin the position which they assume when forming a bend in thecorset-steel and the steel-feedingdevice removed.

Fig. 9 represents partial front and edge views I of one of the steelsafter it has been bent;

and Fig. 10 represents a detail view ofa portion of the stationarytable, showing the inclined way at its periphery for directing thecorset-steels as they are brought successively into position into thesteel-receivingslot of the machine.

The framework of the machine comprises'a base A, side frames at a,rigidly spaced apart by cross-bars a and a top a The top a has SerialNo. 712,374.. (No infidel.)

by shaftsb and c, mounted to rotate in suitable bearings in the sideframes at a, the bearings for the front roll-shaft I) being stationaryandthe bearings for the rear roll-shaft c having a limited slidingmovementtoward and away from the front of the machine.

These rolls B andC are located near the .top

of the machine beneath the steel-receiving opening a An auxiliary frameis hinged within the casing onthe shaft '0, which frame comprises a pairof side plates D D' and a cross-bar (1, connecting their lower ends. A

bending-roll E is carried by a rotary shaft 6, mounted in stationaryhearings in the side plates DD of. the auxiliaryframe, thesaid shaftbeinglocated a short distance. below the I shaft 0 of the rear roll. I I

. A rotarycam-shaft F is mounted in adjustable bearings in the sideframes at a, each of the said bearings of the shaft F being'capa rior to'the side frame with a drive-pulley f by means of which the shaft may bedriven from a source of power. (Not shown.) a

The rotarymovement of the shaft F is imparted to the front roll-shaft Z)by a gear-wheel f on the shaft F between the drive-pulleyf and the sideframe mintetmediate gear-wheels G G, mounted on stub-axlesgg, and agearwheel I), carried bythe end ofthe "said shaft 1). Rotary movement isimparted from the front ro1l-shaft b to the rear rollshaft 0,

whether the rolls are closer to or farther from each other, by agear-wheel b on the shaft 17 and a gear-wheel don the shafts, both ofwhich gears are provided with extra long teeth, so as to permit aconsiderable move- I ment toward and away from each'other without beingdisconnected. Rotary movement is imparted to the lower roll-shaft e bymeans I h, mounted in theside plates D l) of the auxiliary swingingframe.

A swinging movement is imparted to the auxiliary frame by a pair of camsf f carried by the shaft F in position to engage the rear edges of theside plates D D. A spring 61 leads from the cross-bar d of the swingingframe to a bracket d carried by one of the cross-bars a The pivot-shaftc of the swinging frame is caused to slide toward and away from thefront of the machine at predetermined intervals during the swingingmovement of the auxiliary frame to alternately permit the rolls B and Oto engage the rear portion of one steel to bend it and to permit theadvance portion of the next succeeding steel to pass freely between thesaid rolls. This movement is accomplished by providing stop-pins I 1,projecting inwardly from the side frames a a in position to engage thefront edges of the side plates D D at the top of the swinging frame, anda cross-bar 1 mounted in sliding bearings in the side frames at a, whichcross-bar iscaused to engage the rear edges of the side plates D D. Thiscross-bar is adjusted by screws t, extending from the back of the sideframes into engagement wit h the sliding bearings of the said cross-bar.

By adjusting the bar 1 the greatest distance between the rol-lsB and Cmay be regulated to suit steels of different thicknesses, and byadjusting the bearings of the shaft F the amountof bend to be impartedto the steels may also be regulated. t

A stationary table J is mounted on a suitable supportj, secured to thetop of the machine, upon which table is mounted a rotary table J. Thestationary and rotary tables are preferably of disk shape of about thesame diameter.-

The rotary table J" is provided with an annular series of f unnel-shapedhoppers J having their lower ends provided with corsetsteel-dischargeopenings], extended through lar series of abutmentsas, forinstance,holes the rotary table J, so that when the corsetsteels areinserted into the funnels their lower ends will rest upon the stationarytable J.

The stationary table J is provided with a downwardly-extended way orguide 7' at its periphery adjacent to the steel-receiving slot a in thetop a of the casing for directing the lower ends of the several steelsinto the said slot a as they are brought successively into position overthe same. I t

The means which we employ for imparting a step-by-step rotary movementto the table J comprises the following parts: A dog K is mounted toslide forwardly and rearwardly on the top a of the frame, the free endof the said dog being fitted to engage an annuj in the rotary table J.This arm 70 of. the

and its other arm engaged by a cam f, car

ried by the shaft F. The rocking lever L is held in engagement with thecam f by a retracting-spring Z, leading from the lower arm of the hopperto one of the cross-bars a of the frame.

A spring-actuated arm 70 is carried by the top a of: the frame with itsfree end in engagement with. the periphery of the rotary table J. Thesaid table is provided I with notches 70 corresponding to the hoppers Jarranged to receive the end of the, arm 70', so that the said arm mayhold the successive hoppers temporarily in their positions over thesteel-receiving opening a in the top a while the arm 70 of the dog isbrought back into position to engage its next succeeding ble M,h avingdownwardly extended branches m m, which are secured to the side framesat a by bolts m which pass through elongated slots m in the said ears.This stop may be adjusted toward and away from the bending-rolls, so asto determine the point on the steel which is inserted within the machineat which the bend shall be started.

An adjustable discharge-plate N is carried by the auxiliary swingingframe, which plate is provided with ears n at, havingverticallyelongated slots a, through which pass clamping-bolts a forclamping the discharge-plate in any desired adjustment. Thisdischargeplate'N is fitted to engage the advance or lower end of thesteel as the frame is swung forwardly and positively swing the saidsteel outwardly away from the machine as it is being bent, thuspreventing any tendency on the part of the steel to stick in its firstposition within the machine.

In operation the corset-steels to be bent are dropped into an annularseries of hoppers J As the machine is operated the dog K will he slidback and forth by the rocking of the lever L, thus bringing the steelssuccessively into position to drop into the opening a in the top a atthe proper intervals. As each of the steels is dropped from its hopperinto the machine the rolls B and O are moved a distance apart sufficientto permit the steel to fall freely until its lower end rests upon thestop M. The auxiliary frame is then swung forward, thus bringing the tworolls B and G into contact with the opposite faces of the steel and theroll E into engagement with the inner face of the steel to bend itpartially around the roll B. At the same time the discharge-plate N willswing forward and positively free the lower end of the steel from theadjustable stop M. y

By the use of'the plurality of hoppers for feeding the corset-steelsinto the machine the machine may be operated at a highrate of speed,thus turning out a maximum number of bent steelsin a minimum space oftime.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts without departing from the spirit andscope of this invention. Hence we do not wish to limit ourselvesstrictly to the structure herein set forth, but

What We claim is- 1. In a metal-bending machine, a movable device forcontaining a plurality of strips of metal, bending-rolls arranged toreceive the strips between them, means for operating the bending-rollsand means under the control of the bending-roll-operating means formoving the strip-containing device into position to permit successivestrips to fall into position to be engaged by the bending-rolls atpredetermined intervals, substantially as set forth.
